Objects of the ExtFileName type can be used independently of other CADRaster implemented objects. They can be used to collect in one object the following information about a document: file name, format name and compression mode name.
- FileName
Document file name.
Syntax:
Name = File.FileName
Name
STRING value receiving the name of the file associated with the current file object
File
An object expression that evaluates to a CADRaster file object
- FormatName
Document file format name.
Syntax:
Format = File.FormatName
Format
STRING value receiving the format name of the file associated with the current file object
File
An object expression that evaluates to a CADRaster file object
- SubformatName
Document file compression mode name.
Syntax:
Name = File.SubformatName
Name
Name STRING value receiving the subformat name of the file associated with the current file object
File
An object expression that evaluates to a CADRaster file object
- DetectFormat
Sets the FormatName and SubformatName properties based on the FileName property value. When format detection is successful returns 0, otherwise returns -1.
Syntax:
Ret = File.DetectFormat ()
Ret
SHORT value, set to 0 on success, -1 otherwise
File
An object expression that evaluates to a CADRaster file object
- IsRasterFile
Returns TRUE, if the FileName property is the name of a raster drawing file with an extension supported by CADRaster, otherwise returns FALSE.
Syntax:
Raster = File.IsRasterFile()
Raster
BOOLEAN value set to TRUE if the file associated with the current file object is a raster file
File
An object expression that evaluates to a CADRaster file object
- IsVectorFile
Returns TRUE, if the FileName property is the name of a vector drawing file with an extension supported by CADRaster, otherwise returns FALSE.
Syntax:
Vector = File.IsVectorFile()
Vector
BOOLEAN value set to TRUE if the file associated with the current file object is a vector file
File
An object expression that evaluates to a CADRaster file object
- OpenFileDialog
Launches the File - Open dialog box, which allows to select existing files in one of the file formats supported by CADRaster. If a file is selected, its parameters are saved to the specific ExtFileName object properties and the OpenFileDialog method returns 0. If the file has not been selected, the method returns -1.
Syntax:
Ret = File.OpenFileDialog (Caption)
Ret
SHORT value, receiving the selection state in the dialog
Caption
STRING value, that is to be put as the title of the dialog
File
An object expression that evaluates to a CADRaster file object
- SaveFileDialog
Launches the Save As dialog box, which allows to select a destination file for the document. If a file is selected, its parameters are saved to the specific ExtFileName object properties and the SaveFileDialog method returns 0. If no file has been selected, the method returns -1. The property values can be retrieved or the entire ExtFileName object can be passed to the SaveAs method of the Document object as a parameter. Parameters nColors and nPages specify the number of colors and pages in the destination drawing.
Syntax:
Ret = File.SaveFileDialog (Caption, nColors, nPages)
Caption
STRING value, that is to be put as the title of the dialog
nColors
SHORT value, containing the number of colors in the destination drawing
nPages
SHORT value, containing the number of pages in the destination drawing
Ret
SHORT value, receiving the selection state in the dialog
File
An object expression that evaluates to a CADRaster file object
